TAKE-UP AND CATCH BLOCK.

SPECIFICATION forming part of Letters Patent No. 740,070, datedSeptember 29, 1903. hppiiaionnearebrwy14,1903. stiamo'. 143,292.(Nomad.)

T0 all whom] t may concern: Y

Beit known that I, WILLIAM O. F. ZIMMER MAN, of Lonetree, in thecountyof JohnsonY and State of Iowa, have invented certain new and usefulImprovements in Take-Up and Catch Blocks; and I hereby declare thatthefollowing is a full, clear, and exact descriptionl thereof, referencebeing had to the accom.-

panying drawings, which form part of this specification.

This invention is an improved take-up and catch block for ropes andcables, especially designed for use in connection with stumppullingmachines where long cables'are em*- ployed and where it is desirable tohave a device by which the cable can be quickly attached to a stump andthe slack taken 'up in an expeditious manner and which will hold thecable tightly and securely under the great strains to which it issubjected in drawing the stumps. The improved device also does away withthe necessity for an auxiliary or attaching cable, which is ordinarilyemployedV to fasten the take-up to the stumps while the parts of thefianges lsubjected to the greatest strain may be reinforced byradially-disposed ribs. One o f the 'flanges is slotted, so as to permitthe slack end of the cable to be passed out of the groove. From the diskextendsk a radial ar`m,which is stiffened by Iianges,which enable it tobear the enormous strain to which it is subjected, and on the extremityof this arm is a hook, which engages the draft run of the cable, so asto hold the cable around the stump and permit the cable to be quicklyfastened or unfastened thereto without having to lift the cable-loopsover or od the end of stump, a particular advantage of the device beingthat it requires the fewest possible `ofthe device.

Lhasection on line 4t 4, Fig. 1; Fig. 5, a secbends of the cable, noinjurious twists thereof, and no dangerous transverse biting-clampsthereon.

The device will be clearly understood from 'the following` description,in connection with the drawings, which illustrate a preferred Vform ofthe invention, and the appended In said drawings, Figure l is a planview illustrating the combined take-up and catch block in use. Fig. 2 isan enlarged side view Fig. 3 is a bottom View; Fig.

tionon line 5 5, Fig. l.

The combined take-up and catch has a disklike body A, which is formedwith a deep peripheral groove d, whose inner width is preferablyslightly less than the diameter of the cable with which it is employed.At one side of the disk an opening or slot d' is made vfered, as at d2,to prevent the cable being injured by pressure against sharpangles. Fromthe under side of the disk and lower flange thereof extends a radial armB, this arm beii-ng about ninety degrees removed from the notch d', andthe upper surface of the arm loeing preferably about in the same planeas the inner side of the lower flange of the disk, asshown in Fig. 2. Onthe extremity of arm B is an inwardly-extending hook b, the sides of thehook being preferably chamfered, as at h', to prevent Ycutting of-thecable. This arm extends practically'from the center of the disk portionA, but is made integral therewith and is provided withreinforcing-flanges B on its under side edges, said flanges extending toand around the outer side edges of the hook b and impart great strengthand rigidity to the arm to enable the device to withstand the enormousstrains to which it is subjected inpulling stumps.

The arm and flanges also stiffen the lower flange of thedisk at a pointwhere it is subjected to greatest strain, andV the superimposed iiangeis likewise. stiffened at such IOO points and opposite the arm bysubstantially radially-disposed st ffening-ribs as, one such rib 0.4being at the edge of notch a', adjacent to arm B. The lower flange ofthe disk may be further strengthened by radially-disposed ribs a5 atopposite sides of the arm.

Operation: In using the device the pullingcable C, one end of which isattached, for example, to any suitable draft mechanism, such as awinding-drum, has its free end passed around a stump or other object tobe pulled or fastened to. Then the free end of the cable is passedthrough slot ot' into groove a and the take-up turned so as to wrap thecable upon itself in the groove ct until it is wrapped about one and ahalf times around the block, the overlapping portion of the cableextending directly to thestump and pressing the overlapped portion by alateral thrust into the groove a. The hook B is then caught over theadjacent forwardly-extending run of the cable, thus causing it topractically encircle the object, and the more the cable is tautened bypulling thereon the tighter is the cable gripped or held by the block,the cable being held by its friction against the block, which isnon-rotatable, and by the lateral pressure of the overlapping portionthereof against the inner overlapped portion,which is crowded tightlytoward and against the bottom of the groove a'.

The combined slack take-up and catch is particularly adapted for usewith stump-pullersin which the main cable may be two hundred or morefeet long; but by using this take-up the cable can be readily attachedto any object far or near within the length of the cable without loss oftime in taking up slack by driving the sweep or winding-drum, as thetake-up and catch can be used at any pointof the cable, while the hookcatching the draft run of the cable will make a secure snare-loop arounda stump or other object without the employment of any auxiliaryfastening rope or cable, and the cable can be instantly released from anobject when desired by disengaging the' hook and then turning the disk,so as to unwrap it from the cable.

Having thus described myinvention, what is therefore claimed as new, andupon which Letters Patent is desired, is-

1. A combined take-up and catch for cables, comprising a disk having aperipheral circumferential groove around and in which the free end ofthe cable is wrapped, an opening in one of the flanges of the groove forthe passage of the overlapped free slack end of cable, and aradially-extending arm adjacent to the portion of the disk where thecable is overlapped, and an inwardly-turned hook on the outer end ofsaid arm lying opposite the periphery of the disk and adapted to engagethe draft portion of the cable and hold the same looped around anobject, substantially as described.

2. A combined take-up and catch for cables, comprising a disk having acircumferential peripheral groove, in which the cable is wrapped andoverlapped, a notch or opening in one of the groove-flanges for thepassage ofthe free slack end of cable, an integral arm extending fromthe under side of disk provided with a catch-hook on its outer endadapted to engage the draft portion of the cable and hold the cablelooped around an object, said arm and hook having reinforcing sideflanges for the purpose and substantially as described.

3. The herein-described take-up and catch for cables, comprising adisk-like body having a circumferential groove in its periphery, a notchin the top flange of the groove extending to the bottom of the groove,radiating ribs on the upper side of the disk to strengthen the topflange, a radially-extending arm projecting from the under side of thedisk and stiifening the under flange' thereof, opposite flanges on theside edges of said arm to stien the same, and an inwardly'extending hookon the extremity of said arm, the

slack end of cable being secured in the groove of the disk, the cablelooped around an object and the draft portion of the cable being engagedwith the hook whereby the cable can be held clamped around the object towhich it is attached, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I a'ix my signature inpresence of two witnesses.
